Fresh vegetable juice helps supply your body with readily available nutrition. Fresh vegetable juice not only tastes great, but it helps you eat, or in this case, drink more vegetables in a day than you normally would. While juicing allows you to easily consume more vegetables in a day than you would normally eat, you need to be aware that you do not go to the extreme and consume too much juice.
Vegetable juices can contain any vegetables you in any combination! Have fun!
